Reliability and practical aspects of the disease impact measure on hypertensive patients
Insights
The Instrument to Measure the Impact of Coronary Disease on Patient's Daily Life (IDCV) is reliable for hypertensive patients. Further research is needed to refine the "Adjustment to the Disease" domain of this cardiovascular disease impact tool.
Area of Science:
- Cardiology
- Health Outcomes Research
- Psychometrics
Background:
- Hypertension is a significant risk factor for cardiovascular disease.
- Measuring the impact of coronary disease on daily life is crucial for patient management.
- The Instrument to Measure the Impact of Coronary Disease on Patient's Daily Life (IDCV) requires validation in hypertensive populations.
Purpose of the Study:
- To assess the feasibility and acceptability of the IDCV in hypertensive patients.
- To evaluate ceiling and floor effects of the IDCV.
- To determine the reliability of the IDCV for this patient group.
Main Methods:
- 137 hypertensive outpatients were surveyed.
- Sociodemographic and clinical data were collected.
- The IDCV was administered, followed by reliability assessments (temporal stability, internal consistency).
Main Results:
- The IDCV was completed by all participants within 8 minutes.
- A 31.4% ceiling effect was noted in the 'Adjustment to the Disease' domain.
- The IDCV demonstrated good internal consistency (total α=0.83) and temporal stability.
Conclusions:
- The IDCV is a user-friendly and reliable instrument for assessing coronary disease impact in hypertensive patients.
- The 'Adjustment to the Disease' domain warrants further investigation and potential revision.
- The IDCV shows promise for clinical utility in managing hypertensive patients with coronary disease.
Objective:
to evaluate the feasibility, acceptability, the ceiling and floor effects and the reliability of the Instrument to Measure the Impact of Coronary Disease on Patient's Daily Life (IDCV) when applied to hypertensive patients.
Method:
one hundred and thirty seven hypertensive outpatients were interviewed, using questionnaires to collect sociodemographic and clinical data, followed by the IDCV. Reliability was assessed according to the temporal stability and internal consistency criteria.
Results:
the IDCV was applied in 8.0 (±3.0) minutes with 100% of the items answered. A ceiling effect of 31.4% was observed in the domain Adjustment to the Disease. The stability measure was observed for the total score and for all domains. There was evidence of internal consistency of the total IDCV (α=0.83) and the domains Physical Impact of the Disease – Symptoms (α=0.78) and Social and Emotional Impact of the Disease (α=0.74).
Conclusion:
the IDCV is an instrument of easy use and its reliability among hypertensive patients is evidenced. The domain Adjustment to the Disease, however, should be reviewed in further studies.

Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.
